The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

Mucosal surfaces serve as critical battlegrounds where the immune system must balance tolerance to commensal organisms with rapid defense against pathogens.

When a transplanted organ arrives, it’s like a controlled burn that risks becoming a wildfire. The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the ...

The human immune system has evolved throughout history to effectively recognize and adapt to invading pathogens. To combat disease, the human body employs the immune system composed of two separate ...

In a study that further corroborated these observations, scientists found that cyclic fasting in mice improved their antitumor responses mediated by natural killer (NK) cells. 4 The results, published ...

Findings from St. Jude Children's Research Hospital demonstrate that virtual memory T cells, a specialized group of immune cells, provide nonspecific immunity for infants early in life. The work stems ...

In several disease conditions, including infections and cancers, innate immune activation and nutrient scarcity occur together. A study from St. Jude Children's Research Hospital published today in ...

Basophils trigger a cytokine cascade that improves antitumor immunity in mice, offering potential targets for cancer immunotherapy. “The results remind us: Don’t forget the basophil,” said study ...
